Boss Strategy

1) Channel your support on Ryuji (First Phase)

In the first phase, Goro will send out two shadows: Cerberus and Cu Chulainn. After doing so, he casts Desperation on them to buff their attack. However, in doing so, they lose defense. This makes them easier to break.

Take note that Cerberus and Cu Chulainn will have High Counter which will occasionally throw attacks back at you. This may deal heavy damage, especially if you attacked after Charge.

Focus fire them if you can. Use ice attacks to knock down Cerberus with Yusuke or Joker. Or, if you’re using Haru, have Yusuke use Masukukaja and have Haru use One-Shot Kill. Joker will just need to use Melchizedek’s God’s Hand to deal damage or Nebiros’ Maiegaon to put them down.

However, if you’re running Ryuji, Makoto, and Morgana, use Ryuji as your main attacker. Joker and Makoto can rotate roles in attacking and healing while Morgana solely heals. If Joker has either Debilitate (Trumpeter) or Rakunda (any random persona,) you will have an easy time this fight. Ryuji should have Matarukaja and Charge in order to end this battle quickly.

Tip: When I fought him, my Black Frost and Melchizedek did very well. Not only did Black Frost have no weaknesses, he had Ice Amp and Rakunda, which doubled the damage of his Diamond Dust. For healing SP, I used Melchizedek.

2) Goro Akechi (Boss)

When fighting Goro Akechi after Cerberus and Cu Chulainn, he’ll unleash everything he has. This is what Melchizedek or Rangda are for. Goro has Megaton Raid, it also becomes a problem when he uses Charge as well. He’ll have some fixation with Joker so have your healers (be it Morgana, Makoto, Ann) keep him up. He’ll also use a variety of Kouha-attacks which Melchizedek can block. There’s also some Eiga-attacks which Melchizedek will nullify as well.

So much the better if you have Melchizedek running Invigorate 2 and you on SP Adhesive 3. That way, you can replenish your Stamina Points (SP). The effects stack so having to regenerate 12 SP per turn isn’t bad. He’ll use Charge every now and then. When he does, switch to Rangda.

3) Cast magic spells first, then use physical attacks later (Second Phase)

■ When he’s at 50% or more HP

With more than 50% health left, he tanks Physical attacks efficiently with Tetrakarn and performs attacks like Maragion, Negative Pile, and Deathbound.

In comparison to the first phase, his HP and attack will have increased drastically. It is recommended to have Party members who can restore each member’s HP. The party should use magic during the first phase since it bypasses the barrier formed by his Tetrakarn. With Negative Pile having a chance to inflict a party member with Despair, having Energy Drop and Energy Shower to lift its effect will be very useful.

■ When he’s at 50% or less HP

After he has suffered significant amounts of damage, he will now prioritize Makarakarn to handle magic spells. Having Makara Break alongside Tetra Break seems tempting this round, however, it does not offer a significant advantage. Akechi will also start launching multi-target skills like Laevateinn.

Goro Akechi’s second phase emphasizes on damage-dealing with heavy Physical attacks. So, casting Masukukaja helps the party secure the fight. If the party is formed with Yusuke in mind, be prepared to endure Maragion, as Goemon/Kamui-Susanoo-o is weak to it.

  1. “The party should exploit his weakness to magic” is a poor phrase here. Weakness mean something in Persona — when a shadow is weak to something, using it knocks them down and lets you all-out attack. Akechi is not weak to magic in this phase. Please consider rewording that to avoid that confusion!
